Windows API 逐个逐个学(0)---- MessageBox
从《精通 Windows API 函数、接口、编程实例》里摘取下来的实例.分别用VC++与VB6练习.
#include <windows.h> //连接时使用User32.lib #pragma comment (lib, "User32.lib") /* ************************************ * WinMain * 功能 Windows应用程序示例 **************************************/ int WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow ) { // 调用API函数 MessageBox MessageBox(NULL, TEXT("开始学习Windows编程"), TEXT("消息对话框"), MB_OK); return 0; }
VB6 Code:
Private Declare Function MessageBox Lib "user32" Alias "MessageBoxA"_
(ByVal hwnd As Long, _
ByVal lpText As String, _
ByVal lpCaption As String, _
ByVal wType As Long) As Long Private Sub Command1_Click() MessageBox 0, "在窗体一之中调用 MessageBox", "Form1", vbInformation End Sub
